Black CMS Gypsum Granules

Black CMS Gypsum Granules are a gypsum-based soil conditioner supplied in free-flowing granule form. Gypsum is calcium sulphate, a naturally occurring mineral that is mined from the ground. Our grade is about 98% pure and contains roughly 22 to 23% available calcium and 15 to 20% sulphur. The "CMS" name refers to the calcium, magnesium and sulphur nutrition the product is positioned to support. It is sold under the Gypsona brand (product code Gypsona-1010), made in India and used in agriculture as a fertilizer and soil amendment.

Heavy black soils tend to seal at the surface, crack when dry and drain slowly after rain. Black Soil Conditioner CMS Gypsum Granules supplies soluble calcium, which helps clay particles bind into stable crumbs. This improves soil structure, water infiltration and root penetration. In soils with excess sodium, calcium replaces sodium on the clay surface so that sodium can be leached away, which is why gypsum is widely used to reclaim sodic soils. Unlike lime, gypsum does not significantly change soil pH, so it is suitable where you want calcium and sulphur without raising alkalinity.

Crops with high calcium and sulphur demand respond best. Oilseeds such as groundnut, mustard and soybean need sulphur for oil synthesis, and groundnut also needs calcium in the pod zone for good pod filling. Pulses use sulphur for protein and for nodule formation in legume roots. Cereals, cotton, vegetables, fruit and sugarcane also use both nutrients. Sulphur is part of amino acids and plant enzymes, and it supports chlorophyll formation. Calcium supports cell division and strengthens cell walls. Together they aid nitrogen metabolism, phosphorus use and more uniform crop maturity.

Dose depends on the soil test, the crop and the goal. A useful reference is that 100 kg of this product supplies about 22 to 23 kg of calcium and 15 to 20 kg of sulphur. For sulphur-demanding crops, farmers commonly apply a few hundred kilograms per hectare, and for groundnut the usual practice is to apply at flowering or pegging so calcium is available in the pod zone. Sodic soil reclamation needs a gypsum requirement test and much higher quantities. Please follow your local agriculture department or soil laboratory recommendation for your field.

Granules are dust-free, easier to handle and simple to spread by hand, broadcaster or fertilizer spreader. They flow evenly, so coverage is more uniform than with fine powder, which can clump in humid weather or blow away in wind. Granules also blend well with other dry fertilizers and dissolve gradually in soil moisture, releasing calcium and sulphur over time instead of all at once. This makes Black CMS Gypsum Granules practical for large farms and for operators who apply through mechanical equipment.

Black CMS Gypsum Granules are supplied in jumbo bags of 25 to 50 kg, which suit both farm use and bulk dispatch. Store the bags on pallets or a raised surface in a dry, covered area, away from direct rain and standing water. Keep opened bags tightly closed so the granules stay free-flowing. Gypsum is a natural mineral and is generally safe to handle, but wear gloves and a dust mask during loading and spreading, as with any dry fertilizer.
